In this Ordinance:
facility means a reactor, a critical assembly, a conversion plant, a fuel element fabrication plant, a reprocessing plant, an enrichment plant, a storage facility or any other installation at which materials referred to in Article 2 paragraph 1 letter a are normally used in quantities that exceed an effective kilogram;
location outside facilities means an installation outside facilities in which materials referred to in Article 2 paragraph 1 letter a are normally used or stored in quantities that do not exceed an effective kilogram;
site means the area that includes the buildings and installations required for operation of a facility or of a location outside facilities; this includes closed-down facilities and closed-down locations outside facilities, provided hot cells are still installed at these locations outside facilities or activities have been carried out in connection with conversion, enrichment, fuel production or reprocessing;
closed-down facility means a facility that is no longer in operation and in which no materials in accordance with Article 2 paragraph 1 letter a are present, but in which the essential structures and equipment for handling these materials are still available;
decommissioned facility means a facility whose structures and equipment have been removed or rendered unusable to the extent that they can no longer be used to store, handle, process or use materials in accordance with Article 2 paragraph 1 letter a;
effective kilogram means a unit of measurement that corresponds in the case of:
plutonium, to its weight in kilogrammes,
uranium with an enrichment of 0.01 (1 %) or more, its weight in kilogrammes multiplied by the square of its enrichment,
uranium with an enrichment of less than 0.01 (1 %) and more than 0.005 (0.5 %), its weight in kilograms multiplied by 0.0001, and
uranium with an enrichment of 0.005 (0.5 %) or less, and thorium, its weight in kilograms multiplied by 0.00005;
highly enriched uranium means enriched uranium in which the proportion of uranium‑233, uranium‑235 or of both isotopes together amounts to or exceeds 20 per cent;
batch means a portion of materials in accordance with Article 2 paragraph 1 letter a handled as a unit for accounting purposes and for which the composition and quantity of the materials are defined by a single set of specifications or measurements; the material may be in bulk form or in a number of separate items;
terminated material means material in accordance with Article 2 paragraph 1 letter a for which the safeguards based on Article 11 or 13 of the Safeguards Agreement7 have been terminated;
essential equipment means equipment that is essential for storing, handling, processing or using materials in accordance with Article 2 paragraph 1 letter a;
environmental samples means air, water, soil, plant and other samples, including swipe samples;
research and development activities related to the nuclear fuel cycle means, subject to paragraph 2, activities that cover specific aspects of process or system development, in particular:
the conversion and enrichment of materials in accordance with Article 2 paragraph 1 letter a,
the manufacture and reprocessing of fuel elements,
the development of nuclear reactors and critical assemblies,
the processing of intermediate and high-level waste that contains plutonium, highly enriched uranium or uranium‑233, but not repackaging and conditioning for the purpose of storage or disposal, provided that no isotopes are separated in the process.
The following are not considered research and development activities related to the fuel cycle in accordance with paragraph 1 letter l:
activities related to theoretical or basic scientific research;
research and development:
on potential industrial uses of radio isotopes,
for medical, hydrological and agricultural applications,
on the effects on health and the environment, and
for improved maintenance.
